Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Calves' liver
Main protein; cooks quickly and becomes tender when it is not overcooked.
Onions
Sweetness and aroma as they soften and brown in the hot oil.
Oil
Conducts heat to the liver and gives it a browned, crisp surface.

The step that matters

Dry the liver thoroughly. Surface moisture steams the liver instead of letting it brown in the hot oil. Patting it dry before frying gives better colour and a more even sear.

Swap the onion

How well each one fits the dish's main ingredients (liver, milk):

  1. Potatofits better
  2. Onionthe original
  3. Tomatofits about as well
  4. Capsicumfits about as well

Fit is the average pairing score against liver, milk. Candidates are from the same food group and used in at least 100 recipes.
